Not with a 400Mhz ARM9 processor on a fairly high res display. In these case basic old things like color expansion for font rendering, bit blits and solid fills for scrolls work beautifully. Anyway I just realized that the ARM side of the AST GPU doesn't have the accel bits at all anyway, only the host side, so I'm back to just a dumb FB. I still want to avoid the copies though. > It's a feature > that kernel ppl obsess over but I don't get a lot of real world feedback, > (booting 9000 scsi nodes with debug on takes a long time was possibly > something I heard once, and I think we resolved).
